Beit known that Ldosnrn H. ULLMAN', a citizen of the United States,residing at New Haven, in the. county of New Haven and State ofConnecticut, have invented certain new and useful Improvements inIroning. Machines, of which the following is a speciication. f

My present invention Apertains .to ironing machines, the constructionand advanta es4 of' which will be hereinafter set forth, re erence'being' had to the `'annexed Ydrawings,-

wherein:

Figure 1 is a. sectional elevation .of the mafchine, the` ports being ina positionof .rest and the iron fully elevated at what may be termedthe' rear `of the inward stroke;.F1g., 2v a vertical sectional view,taken on the line 2-2 of Fig. 6, the parts being in operativev positionand the. iron making its. outward or forward stroke; Fig. 3 a sectionalelevation oft-he upper portion of the machine, the full-line positionshowing the iron as having nished its 'outward stroke and raised fromthe board or support, and the dotted-line position the same relation orposition at the end of -the inward stroke; Fig. 4 a detail sectionalVview of the clutch mechanism, taken on the line 4-4 ot Fig. 1., tbeparts being. slightly enlarged; Fig. 5 a, detail per spective view ofthe rocker which elevates the iron-carrying bar or rod; Fi l. |65v atransverse vertical sectional View on t eline 6--6 of Fig. 1; and Figs.7 and 8 side and plan views. respectively, of the' clutchaeleasing andstop arm` The mainobject of the present invention is to produce anironing machine, adapted more especially for the ironing of corsets andthe like, in which the iron will be elevated from the goods at the endof each forward and rearward stroke whereby the o erator may readilyshift the goods upon vt e table or support while the iron is soelevated.

A further object; of the'inventionis-to provide a mechanism which, whenthe operation of the machine is to be stopped, will bring the iron torestin its fully elevated position and, preferably, when it is at theend of its inward or rearward stroke.

In the drawings,'l denotes a suitable stand or bench upon which ismounted an ironing-board ortable. 2,l with which theiron 3 adapted tocoact. The. iron is prefery ably Yelectrlcally heated and is connectedto an actuating bar Aor rod 4 through a yoke 5, pivotally connected totbe-outer end of the. bar, the yoke in turn being likewise connectv edtothe iron, through the agency of a pivot-.4 I pin 6. Said bar, as. willbe best.. seen upon reference to Fig. 6, passes between and is I ,sg'uided4 by the upright members 7 and 8` of a :standard or frame 9,extending upwardly I from a base plate or casting 10, secured to f thestand or bench 1. The rear end of bar/1 is pivotally connected to theupper end of av lever- 1l which latter is fulcrumed upon a shaft 12.which finds its support in gear-supi porting frame or housing 13,secured upon the floor beneath. the bench 1.. Extending :through saidhousing is La drive shaft 11.1., havin secured thereto axed Aclutchmember .'15, a apted to coact with a sliding clutch .member 16, formedintegrally with or at- .tached to ax. inion 17.. The sliding clutchmember may e thrown into and out of locking engagementwith member 15through the agency of shifter- 18 which is actuated through the agencyof n lever 19. Normally this 'clutch will remain in" locked position, asg I employ a se arate clutch to bring the iron i to rest'. in its eevated position. Pinion 1,7 is in constant mesh with a ear 2O secured tol shaft 21, which likewise as ke ed to it `a pinion 22, Fig.`1, saidpinion mes ing with a gear 23 secured u n a'shaft 24. Said shaftprojects outwar y beyond the housing or frame 13, see Figs. @and 6, .andcarries a clutch member 25, said member in the form shown being formedintegrally with the said member, said openings being adapted to coactwith a locking pin or bolt 27, mounted in a recess formed in acranlo'disk 28. A spring 29, mounted inte'riorly of the pin and bearingat its outer end against a screw plug 30, secured' in the crank-disk,-urges the boltI into locking lengagement. with the clutch member.or-perforate disk 25. Bolt 27' is formed with a laterally-extending lugor linger 31 which is cut away and beveled as at 32, Fig. 7, to permitthe retract-ing' member,

shaft. A series of openings 26y is formed in 1Q to the inner end of thetreadle vand at its up er end is likewise connected to the. outer.

en of a clutch-releasing'andI stop arm or lever 38. Said lever isfulcrumed on a rod 38a Fig. 2, and the free end thereof stands in linewith lug 31 of the boa 27, said end bein curved, see Fig. 7, and'formedwith a beve Aed oninclined face 39, which terminates adjacent a stop lug40.

' When the machine is at rest, lug 31 contacts with lug 40, the beveledend 32 having passedl into contact with'the inclinedface 39 andwithdrawn the bolt 27 ,the parts then bein in the position shown in Fig.4, the cran disk being at rest and held against any movement owing tofriction of the shaft 24 and disk 25, which still continue to rotate.`This disengagement takes place when the operator removes his foot fromthe treadle.

l Pivotally connected to lever 38 and eX- tending upwardly therefrom isa link 41, said link havin a slot 42 formed in the upper end thereo andinto which extends a pin or screw projecting outwardly from an end of ashaft 44 journaled in' theuprights 7 and 8. A V-shaped rocker, having arelatively short arm and a long arm 46 is secured to said shaft, and asprln 47 tends to 40 .move the shaft clockwise an to thereby bring theshort arm to a substantially vertical position Fig. 2.

Extending downwardly from bar 4, adjacent its inner end, is a lug orbracket 48 a second bracket having a short arm 49 and. a klonger arm 50,being likewise secured to the bar adjacent. its outer end and the ironcarried thereby. 'These brackets coacting ,with the rocker serve toelevate the bar 4, 50 and consequently .the iron, in the followingmanner: When the operator depresses the treadle, as in Fig. 2, theclutch lever 38 is withdrawn from engagement with bolt 27,'

the parts moving from the position shown in Figs. 1 and 6 l(where theyare'at rest) to the position illustrated inFig. 2. When the bolt passesinto one of the openings 26,

A crank disk 28 is locked to shaft 24 and rotated therewith;consequently, lever 11 will be drawn forward and bar 4 pushed outwardly.As bar 4 moves forwardly, the rocker also swings forwardly, arm 46moving downwardly with the bar, and the iron comin to rest uponthe goodsor article 65 upon t 1e table 2. The parts are then in the armorlever'43 secured to the protrudingv positions shown in Fig. 2, the shortarm 45 of the rocker Swingin upto substantially a vertical position and'1n the path of bracket 48. As b ar 4 nears the limit of its outwardmovement, said bracket contacts with the .70 arm 45, said arm thenacting as 'a fulcrum,

see full line position, Fig. 3, and' causingthe outer end of the bar tobe. elevated and the iron to be raised or lifted clear of the board.LUpon the return movement of the( bar, the rocker is drawn or swunlrearwardl by contact with the bar, an ceases to ho d the same elevated,the iron being lowered and resting on the board during its return orinward movement. The parts are so proportioned that during the movementsthereof and while the iron is uponthe board thepin upon--lever or crank43 does not contact with the upper end wall of slot 42, spring 47 atsuch time serving to turn the rocker forwardly and bring arm 45into-contact with the under faceof the bar 4,I see Fig. 2. When theparts arein this position', and the ironcarrying bar 4 is' movininwardly the forward end of arm 46 of t e rocker will lie in a planebelow arm 49 land clear thesame, finally coming into contact with thelonger arm 50 and being rocked rearwardly thereby. This causes the'arm50 to lift the ironcarrying bar as said bar' reaches its limit of inwardmotion. Upon a reversal .of the directionV` of movement of bar 4, therocker will swin forwardly, thereby lowering the bar and t e iron, thelatter travelingI over 100' the board until it reaches its limit ofoutwardv movement, when it will be again elevated. This cycle of oerations continues until the operator 4relldases the .treadl. When' thisis done, the clutch-releasing le- 105 ver moves up into the path ofthebolt 27, and withdrawing it releases crank disk 28 from the drivingshaft 24. Atl the same time, link 41 is drawn down and the end thereofengaging the pin on lever ,43, holds 1,10

the rocker against forward movement'in opposition t0 sprin 47,v therebyholding arm 46 in the path o the short arm or projection 49 of theforward bracket. Shortly after these arms contact, which they do just-before the clutch connection is broken, bar

4 will be elevated to lits Vfull extent, as shown 1n 1, the machine thencoming to rest. B li ting the iron to a considerable extent w enit'reaches its limit of inward move- 120 ment and comes to rest, thetable is left substantially unobstructed, and a new cover or felt may beplaced `on the board vwithout fear on the part of the operator of being:burned by the iron.

It is, of course, conceivable that the connection betweenthe rocker andthe clutcliwithdrawing lever ma be omitted, in which event the rockerwou d act only upon'the brackets or projections 48 and 50, the for- 13Cward long arm ofthe rocker under. such conditions being held bylthe-rocker spring out of the path 'of member 49 at all times.

Having thus described my invention, what Iclaim-is: j.'
